PATENT JOHN F. DIEMER, OF ELIZABETH, NEYV JERSEY.

PAPER Box.

SPECIFICATION forming part of Letters Patent No. 368,819, dated August23, 1887. Application filed February 14, 1887. Serial No. 227,548. (Nomodel.)

To all whom it may concern.-

Be it known that I, JOHN F. DIEMER, of Elizabeth, Union county, andState of New Jersey, have invented a new and Improved Paper Box, ofwhich the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved paper boxwhich is simple and durable in construction and can be folded up forconvenient transportation.

The invention consists of a box-body having flaps which are locked inplace on a metallic plate of-peculiar construction.

The invention alsoconsists of various parts anddetails and combinationsof the same, as will be fully described hereinafter, and then pointedout in the claim.

Reference is to be had to the accompanying drawings, forming apart ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of the boxbody with the flaps extended.Fig. 2 is a similar view of the same folded together. Fig. 3 is aperspective view of the looking-plate. Fig. 4 is a perspective View ofthe finished box, parts being broken out. Fig. 5 is a crosssection ofthe bottom of. the finished box, and Fig. 6 is a similar cross-sectionshowing the locking-plate in position before its flaps are closed.

The box-body A consists of the usual four sides, B, B, B", and B", eachprovided with a flap, a, a, a and a", respectively. The two oppositeflaps a and a are of equal length, and each extends from one side of thebox to the other. The other flaps, a and a", are also of equal length,but are shorter than the flaps a and a and do not overlap each otherwhen extended in a plane, as shown in Fig. 5.

The locking-plate G is provided on two opposite sides with right-angularflanges c and c", and is provided on the two opposite ends with theflanges c and c extending at right angles from the said locking-plate(3, but in an opposite direction from the flanges c and c, as shown inFig. 3. The locking-plate O corresponds in size to the crosssection ofthe box body A.

The box is formed by first bending the flaps a and a at right angles totheir respective sides and toward each other, as shown in Fig. 5. Thelocking-plate O is then placed on top of the flaps a and atso that thetwo flanges c and c of the plate extend into the box-body, as shown inFig. 6. One of the flaps a or a of the box-body is then bent over uponthe locking-plate O, and then the other respective flap, a or a is bentdown over the first flap on the locking-plate. The inner flanges, c andc of the lockingplate C are then bent toward eachother and over theflaps a and a, and

then the-outside flanges, c and 0 are bent similarly over the flaps aand a", as shown in Figs. 4. and 5.

It will be seen that the inner flanges, cand c lock the flaps a and a inplace on the inside of the locking-plate 0, while the outer flanges, cand c lock the other two flaps, a and a in place on the outside of thelocking-plate 0, thus forming a strong and durable bottom for thebox-body.

The box is open at one end, and can be used single or with a sliding boxfor various purposes, especially for storing letters and otherdocuments.

For letter or file boxes I form the front of the casing which slidesinto the hox-body-in the same manner as before described, and thensecure a ring or knob to the front, in the usual manner.

It will be seen that I am enabled to fold the box-body A flat, as shownin Fig. 2, thus perbox-body, in combination with alockingplate providedon two opposite sides with flanges and on two opposite ends with similarflanges extending in opposite directions from the said side flanges,substantially as shown and described.
